Lettera Patent' llo. 63,520, dated April 2, 185 Mm- @te tlgehnlr refresh tu in tigers jtta atmt nnb uniting un nf tlgc time..

Be it known that I, TRUMAN HOTCHKISS, of Stratford, in the State of Connecticut, have invented a new and useful mplovelnent in Friction-Rolle or Wheels, of which the following, with the accompanying drawings, is a full description.

Figure 1 is a side elevation.

Figure 2 is a vertical section, at right angles to the axis.,

My invention is intended to operate where there is u pressure to be exerted in the direction of the axis or spindle, and is useful for propellers7 turn-tables7 or other cases where the spindle revolves. It consists of a. loose collar placed upon an axis, with u series ofrndialaxes extending from the coller outward, upon which are placed loose wheels retainedupon these axes by screws inserted in their ends. The periphcries of these wheels revolve upon permanent or fixed shoulders or collars or plates through which the main axis passes.

In the drawings, a is the main axis, passing through the uprights 72 in the frame A A. collar placed upon the main axis between the uprighte and between the fixed plate 2 the main axis. Radiating from the loose collar 6 is a series of axes, c e c e. Upon these axes are placed loose wheels e e e e, which are held on by means of the heads of screws d d d d, which are inserted in the radial axes. C represents a, propeller onthe end of the main shaft.

When used for this purpose, the push ofthe propeller being towards the frame, the wheels and collar operating as described, the friction will be greatly lessened.

What I claim, and desire to secure by Letters Patent, is-

The loose collar and Wheels, constructed and operating substantiallyl as described.

In Witness whereof I have signed my name to the above specification and claims.

TRUMAN HOTGHKISS,

bbis e. loose and a fixed collar, B, upon Witnesses:
